Frequently asked questions
What additive manufacturing process is Avimetal 18Ni300 designed for?
Avimetal 18Ni300 is specifically optimized for Laser Powder Bed Fusion (LPBF / SLM), with controlled particle size, flow characteristics, and chemistry to support stable processing and repeatable results
Is Avimetal 18Ni300 Powder suitable for production and serial manufacturing?
Yes. The powder is production-ready and designed for repeatable builds, batch-to-batch consistency, and qualification workflows required in aerospace, defense, and industrial production.
What heat treatment routes are supported?
Standard solution treatment and aging cycles are supported to achieve ultra-high strength and hardness. Heat treatment parameters can be tailored depending on target mechanical properties and application requirements.
Are the mechanical properties listed achieved in the as-built condition?
No. The listed mechanical properties are achieved after appropriate heat treatment, which is essential for unlocking the full performance of 18Ni300.
How does oxygen content affect LPBF performance?
Low oxygen content (≤450 ppm) improves powder flowability, reduces oxidation-related defects, and contributes to consistent melt pool behavior and mechanical properties.
Can this powder be reused in LPBF processes?
Yes. When handled and monitored according to standard powder management practices, Avi Metal 18Ni300 supports controlled powder reuse. Requalification protocols are recommended for critical applications.
